WILLIAM BLANKNER, OF AURORA, ILLINOIS, ASSIGNOR OF ONE-HALF TO CHARLES M. OOATS AND VCHARLES E. CORLETT, OF SAME PLACE.

SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 524,304, dated August 14,1894.

Application tiled March '7, 1894.

n .To all whom it may concern.-

Be it known that I, WILLIAM BLANKNER, a citizen of the United States,'residing at Aurora, in the county of Kane and State of Illinois, have invented a certain new and useful Improvement in Sad-Irons, of which the fola lowing is a specication.

Myinvention relates to the improvement of sad irons and has particular relation to that class of sad irons known as self heating irons, and the objects of my invention areto provide an iron of this class of improved construction and arrangement of parts; to admit of the employment of a constant gasoline iame for heating said iron and to produce other improvementsin details of construction which will be more fully pointed out hereinafter. These obj ectsI accomplish in the manner illustrated in the accompanying drawings, in which-.

Figure l is a side elevation of my improved iron. Fig. 2 is a central vertical section ofthe same and Fig. 3 is a detail view partly in section and partly in elevation showing a modiication in the form of the smoothing plate or iron bottom. l

Similar letters refer to similar parts throughout the several views.'

a. represents the body of the iron which, as indicated in the drawings,`is substantially of a cup or shell shape. From the flat bottom a of this iron bodyrise at desirable intervals posts or bosses a2 which posts or bosses support, as shown, a horizontal plate as within the shell a. From this plate on the outer sides of said bosses a2 rise the vertical supporting arms b of a cover plate b', said cover plate being by means of said arms b elevated slightly above the open upper side of the shell aand having the greater portion of its upper surface depressed, as indicated iuFig. 2 of the drawings. This cover plate is provided at 0pposite ends with short outwardly projecting arms h2 with which are connected at b3 and upon which are supported the ends of a semicircular handle c which rises therefrom. This handle which is in the form of a tube closed at both ends is adapted to serve as a reservoir and has formed therein a supply opening c which is normally closed by a suitable plug c2.

The lower end portions of the reservoir are made to connect by means of a cross pipe c3 Serial No. 502,605. (No model.)

by means of which a uniform amount of oil is retained in both sides of the handle. The depressed upper surface of the top plate h is L tral gas tube e the open upper end of which passes through said plate b and insulating material and projects slightly above the latter. This upwardly projecting end portion of the tube e is provided with short` vertical slots or saw cuts e while the lower open end por# tion of said tubewhich extends to a point a short distance above the bottom ctis notched at regular intervals, as indicated at f. With the shell bottom a I form centrally an upwardly extending conical projection f', the tapering end portion of which projects centrally within the lower end of the tube c. Upon this tube e above said lower end portion l provide a detlector plate indicated at g, said deector plate preferably being formed with downwardly inclined or flaring ears or lugs g formed by the production of notches at regular intervals in the periphery of said plate. Surrounding the'tube c immediately above the plate g is an oil cup g2 the latter having in one side an inlet pipe or tube g3 which extends outwardly and upwardly passing through an opening in the side wally of the shell o, and terminates in an upturned end portion g4 on the outer side of said shell wall.

From one of the lower'end portions of the hollow handle c extends inwardly and thence downwardly a pipe h, said pipe being provided, as indicated at h', with a suitable valve tube to be operated by an external handwheel h2 connected with a valve stem h3.' The downwardly extending portion of the pipe h passes, as shown, throughthe plate b and at a point immediately above and upon the internal plate 0,3 is provided with a curved arm or horizontal extensionh, which extending upon and above the plate a8 passes, as shown, about one side of the tube e. At its remaining end this horizontal pipe h4 is connected to the lower end of an upwardly exj tending gas pipe fi, the latter passing upward and outward through the plate b and insulating material d and at vits upper end being IOO . c onnected with a short pipe i2 which extends is thus supported, as shown, immediately i through the needle point opening 5.

above the upper open end of the central pipe e. At the junction of the pipe sectionst' and t2 is provided a valve k by means of which the degree of communication between said pipes e and t2 is regulated, said valve consisting of the stem 7c and hand wheel k2. In the vertical valve pipe i3 I provide a vertical valve stem i* which controls a needle point opening t5 in the lower end of said Valve pipe.

As indicated at m I provide my improved iron with a detachable smoothing or base platel which has formed in each end thereof a notch or socket m. With the shell or iron body a I provide at one end thereof a downwardly and thence inwardly extending hook n which, as shown, is adapted to engage with one of the notches m of said detachable base plate and to the opposite end of said iron body at a point above the bottom thereof I secure one' end of aspring catch arm fn which extending downwardly has an inturned end portion n2 which is adapted to engage with the remaining notch m of the iron base m. As indicated in Fig. 3 of the drawings the lower surface of the smoothing plate m2 may be curved in the arc of a circle and said curved surface provided with transverse i'luting grooves indicated at 0, the teeth between said iiuting grooves being adapted to enter corresponding grooves in a horizontal iiuting plate o having corresponding grooves and teeth on its upper face as indicated at 02.

In the side wall of the shell a I provide at desirable intervals air openings p.

The manner of utilizing myimprovedirons and operating the same is substantially as follows: The oil which isintroduced into the hollow handle or reservoir c through the opening c is allowed to i'low outwardly therefrom through the pipe 71, the flow being regulated bythevalve h. From this pipe h the oil is conducted through the generator pipe h4 which communicates with the vertical pipe e'. The cup g2 being filled with oil through the medium of the feed pipe g3, the oil contained in said cup is ignited by a flame which may be communicated thereto through said pipe g5 or through one of the side openings p of the shell. Sufficient heat is imparted from the burning oil in the cup g2 and from the plate as which is heated thereby to generate gas within the generator pipes iand t'. The gas thus generated is allowed to pass through the valve opening which is controlled by the valve 7.a thence through the pipe t2 and into the valve pipe t3 and the Valve of the latter being sufiiciently opened the gas is dischald e gas which is thus discharged f rom the lower end of said valve and pipe z3 passes downward through the central tube'e and outward about the Haring surface of the conical pro- Jeetion j" at which point the gas may be lighted through the liame ot' a match inserted through the openings p. The heat from this flame which is deflected downward by the plate a3 and deiiector plate g results in the shell bottom and the base plate which is connected therewith being uniformly and thoroughly heated in a comparatively short space of time.

By regulating the flow of gas through the pipes 712 and 3 which may be accomplished by the proper manipulation of the valve stems lo and 4, it is evident that the volume of flame which issues from the lower end of the tube e may be regulated thus regulating the degree of heat imparted to the iron bottom. From this operation it will be seen that the iron while in use may have imparted thereto a uniform degree of heat and that the iron may be used continuously without the necessity of 11e-heating the same at intervals and without the necessity of burning or otherwise injuring the smoothing face of the iron base by exposing it to a direct heat.

It will be observed that the parts rof my improved device are conveniently and compactly arranged so as to result in the iron presenting a neat external appearance and that said iron may be produced at a reasonable cost of manufacture.

Having now fully described my invention, what I claim, and desire to secure by Letters l. In a sad iron the combination with the -shell a, a horizontal plate as supported therein, a top plate b supported above said' shell, a central burner tube b passing downward through said top plate and internal plate a3 and a delector plate g on said tube, of a hollow handle rising from said-top plate, a valve pipe supported above said burner tube, a horizontal pipe section h4 supported within said shell upon the plate a3 one end ot' said horizontal pipe communicating with the hollow handle c and the remaining end thereof communicating with said valve pipe and a valve controlled orifice in said valve pipe, substantially as and for the purpose specified.

2. In a sad iron the combination with a shell a, a central conical projection f in the bottom thereof, a top plate supported above ,Said shell, a hollow handle rising from said IOO IIO

top plate, a central tube e passing through and depending from said top plate the lower end of said central tube surrounding the upper portion of said vertical projection and a deflector plate g on said tube, of a valve pipe supported vertically above the burner tube e, a horizontal pipe 71,4 within the shell one end of the pipe 4 communicating with said hollow handle and the remaining end with said Valve pipe and a valve controlled oriice in said valve pipe, substantially as and forthe purpose specified.
